7050 T7451 Round Bar
The 7050 T7451 round bar is made from high-strength aerospace-grade aluminum alloy, combining excellent strength, toughness, and stress-corrosion cracking (SCC) resistance. This material is specially heat-treated to maintain its mechanical properties even in thicker sections, making it an ideal choice for critical structural applications.
What is 7050 T7451?
- T7451 temper combines over-aging (T74) with mechanical stress relief, optimizing SCC resistance and dimensional stability, making it suitable for critical applications.
- T7: After solution heat treatment and artificial aging, this temper enhances SCC resistance, with peak strength slightly lower than T6.
- 51: Stress relief through stretching (typically ~1-3% permanent deformation) to minimize residual stresses from the manufacturing process.
7050-T7451 round bar is a high-quality aerospace-grade aluminum alloy that achieves the best balance between strength, corrosion resistance, and machinability. Its T7451 temper ensures reliability in high-stress, corrosive environments, making it an ideal choice for critical structural applications.

7050 T7451 Round Bar Characteristics
- High Strength and Toughness: 7050 alloy offers a high strength-to-weight ratio, and its toughness ensures reliability under high stress and fatigue conditions.
- Enhanced Corrosion Resistance: The T7451 temper design provides better stress corrosion cracking (SCC) resistance and excellent exfoliation resistance, which is particularly important for aerospace and other high-performance applications.
- Thick Sections Can Be Heat Treated and Stabilized: 7050 aluminum is less sensitive to quenching than many other high-strength alloys. This quality means that even when producing heavy or thick sections, it retains its strength and mechanical properties, which is highly beneficial for parts such as fuselage frames, bulkheads, and wing skins.
- Stress Corrosion Resistance: Due to the T7 temper, it performs better than T6.
- Machinability: Performs well when using appropriate tools (hard carbide tools are recommended).
